(a) The power to determine and approve variations is reserved to the City Council and shall be exercised only by the adoption of ordinances. No variations shall be made without a hearing before the Board, or such other body as determined by the City Council.
(b) Variations may be granted by the City Council if the latter determines that the general purpose and intent of the Zoning Ordinance will be complied with.
(c) The Board shall not decide or recommend variations in the provisions of the Zoning Ordinance, unless it shall have made findings based upon the evidence presented to it in the following cases:
1. That the property in question cannot yield a reasonable return if permitted to be used only under the conditions allowed by the regulations governing the district in which it is located; and that the variation, if granted, will not alter the essential character of the locality; or
2. That the plight of the owner is due to unique circumstances; and that the variation, if granted, will not alter the essential character of the locality.
(d) For the purpose of supplementing the above standards, the Board, in making its decision or recommendations whenever there are practical difficulties or particular hardship, shall also take into consideration the extent to which the following facts favorable to the applicant, have been established by the evidence that:
1. The particular physical surroundings, shape, or topographical conditions of the specific property involved would bring a particular hardship upon the owner as distinguished from a mere inconvenience if the strict letter of the regulations were to be carried out.
2. The conditions upon which the petition for variation is based would not be applicable generally to other property within the same zoning classification.
3. The purpose of the variation is not based exclusively upon a desire to make more money out of the property.
4. The alleged difficulty or hardship has not been created by any person presently having an interest in the property.
5. The granting of the variation will not be detrimental to the public welfare or injurious to other property or improvements in the neighborhood in which the property is located.
6. The proposed variation will not impair an adequate supply of light and air to adjacent property, or substantially increase the danger of fire, or otherwise endanger the public safety, or substantially diminish or impair property values within the neighborhood.
(e) The Board may require or recommend such conditions and restrictions upon the premises benefited by a variation as may be necessary to comply with the standards set forth in this section to reduce or minimize the injurious effect of such variation upon other property in the neighborhood, and to implement the general purpose and intent of the Zoning Ordinance.
(f) The City Council may refer any proposed variation back to the Board for further consideration.
(g) Any proposed variation which fails to receive the approval of the Board of Appeals, said approval meaning the affirmative vote of four members of the Board, shall not be passed by the City Council except by the affirmative vote of two-thirds of all the Aldermen of the City.
(h) Every variation shall be made after a hearing before the Board, and shall be accompanied by findings of fact which refer to any exhibits containing plans and specifications for the proposed variation. The findings of fact shall specify the reason or reasons for making the variation. The terms of relief granted shall be specified in the ordinance, and may be conditioned upon such specific terms as are determined by the City Council.
